GEORGE CLAUSING, OF PORTSMOUTH, OHIO, ASSIGNOR TO THE VULGAN LAST COIVL IPANY, 0F PORTSMOUTH, OHIO, A CORPORATION OF OHIO.

LAST.

Original application filed. May 28, 1925, Serial No. 33,352, which has matured into Patent No. 1,586,409. Divided and an application filed January 18, 1926, Serial No. 81,959, which matured into Patent No. 1,592,422. Said last applicationcivided and this application filed June 9, 1926. Serial No. 114,810.

My invention relates to lasts, and particularly to collapsing lasts, and is a division of my application filed Jan. 18, 1926, Serial No. 81,959.

It is the object of my invention to provide a collapsing last with the parts pivotally mounted one on the other moving about a given center of movement with such parts connected together by a solid link, the ends of which are adapted to yield or open to permit the movement of the last parts from one position to the other and to hold them in a given position when so moved.

It is my object to provide a flat spring plate having such yielding ends as to permit of the movement of the last parts and to yieldingly resist such movement.

It is a further object to provide a straight plate link the ends of which permit of this yielding feature thus eliminating a spring.

It is a further object to mount this plate with the spring ends on anchor pins so arranged that a line drawn between the centers thereof will pass over the center of movement of the last parts when the parts are moved and the ends of the link are flexed.

In the drawing I have shown a last embodying my invention.

Referring to the drawing in detail, 1 is a toe part having a slot 2 for accommodating the link. The rear face of the toe part is designated 3. Located transversely oi? the rear face 3 of the last part 1 and across the opening of the slot- 2 is a. semicylindrical groove 4- for receiving the PI'OJGCUHQ circular shoulder or knuckle 5 carried by the heel part 6, on the forward face of. this heel part which is vertical at 7 to form a shoulder abut-ting against the shoulder 8 of the toe part, but this face is cut away at 9 to permit of the collapsing of the last parts. The heel part is provided with a slot 10 for receiving the link which consists of a fiat plate having a solid central portion 11 and end portions which are mounted on the anchor pins 12 and 13 transversely of the slots 10 and 2. These anchor pins are so located that a line drawn between the centers there of will be below the center of movement 14- when the parts are in expanded position and above such point when the parts are in collapsed position. The ends of the links are provided with enlarged ends 15 having centrally located slits 16 which extend inwardly to the bases of V-shaped slots 17 in which are located the anchor pins 12 and 13. lVhen the parts move over dead center these slits 16 open by reason of the pressure of the pins 12 and 13 against each side of the ends 15, as will be apparent from an inspection of the drawing, and either side 01: the ends 15 is spread apart or flexed yieldingly.

It will be understood that I desire to comprehend within my invention such modifications and changes as may be necessary to adapt it to varying conditions and uses.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a last, a heel part and a toe partadapted to rock about one another about agiven point, a plate link of substantially rec tangular form, anchor pins for the ends of said link, the ends of said link being arranged to yield and flex when the parts are removed from one position to the other, said flexing being permitted by V-shaped slots in the ends or said link and slits in said link associated with said slots to permit portions of the link to spread.

2. In a last, a toe part and a heel part adapted to rock one on the other, a plate link with an inflexible center portion and flexible ends, anchor pins in each of said parts for supporting said link, said anchor pins being normally located in the base of outwardly disposed if-shaped slots cut in the ends of said link, said link being severed by a slit at each end from the anchor pin out wardly from the base of the slot to the end of the link, said slit being located between the arms of the l-shaped slot.

In testimony whereof, I aiiix my signature.

GEORGE CLAUSING.
